When using trap on SIGTERM the script will not react to the SIGTERM signal sent while a child is executing.
I.e, the following script does not react on SIGTERM sent to it if it is
waiting for sleep to finish:
```
trap "echo Handled SIGTERM" 0 2 3 15
echo "Before sleep"
sleep inf
echo "After sleep"
```
Instead, trap only on EXIT which covers also a scenario with exit on
SIGINT, SIGTERM.

Why I did it
Fixes#8980 partly.
The corresponding changes in sonic-sairedis is here :
Azure/sonic-sairedis#975
How I did it
Include changes from both repos and build an image for verification.
How to verify it
Trigger fast-reboot with the changes, see the attribute SAI_SWITCH_ATTR_UNINIT_DATA_PLANE_ON_REMOVAL being set at the SAI level.

* buildimage: Add gearbox phy device files and a new physyncd docker to support VS gearbox phy feature
* scripts and configuration needed to support a second syncd docker (physyncd)
* physyncd supports gearbox device and phy SAI APIs and runs multiple instances of syncd, one per phy in the device
* support for VS target (sonic-sairedis vslib has been extended to support a virtual BCM81724 gearbox PHY).
HLD is located at b817a12fd8/doc/gearbox/gearbox_mgr_design.md
**- Why I did it**
This work is part of the gearbox phy joint effort between Microsoft and Broadcom, and is based
on multi-switch support in sonic-sairedis.
**- How I did it**
Overall feature was implemented across several projects. The collective pull requests (some in late stages of review at this point):
https://github.com/Azure/sonic-utilities/pull/931 - CLI (merged)
https://github.com/Azure/sonic-swss-common/pull/347 - Minor changes (merged)
https://github.com/Azure/sonic-swss/pull/1321 - gearsyncd, config parsers, changes to orchargent to create gearbox phy on supported systems
https://github.com/Azure/sonic-sairedis/pull/624 - physyncd, virtual BCM81724 gearbox phy added to vslib
**- How to verify it**
In a vslib build:
root@sonic:/home/admin# show gearbox interfaces status
PHY Id Interface MAC Lanes MAC Lane Speed PHY Lanes PHY Lane Speed Line Lanes Line Lane Speed Oper Admin

In addition, docker ps | grep phy should show a physyncd docker running.
